Before the holidays, author Beth Revis announced an out-of-this-world campaign to promote the release of the third and final book in her Across the Universe series: If fans pre-ordered more copies of Shades of Earth (out today) than they did for books one and two combined, Revis and Penguin would launch a copy of Across the Universe into space. Today, we can reveal that fans rose to the challenge. After the jump, watch the book as it makes its trek to the great beyond (set to the music from 2001: A Space Odyssey, natch).

Pretty cool, right? Are you excited about Shades of Earth? Sound off in the comments.
